For Greenlawn, NY water slide rentals, we recommend booking at least 2-3 weeks in advance, especially during peak summer months when demand is highest. Weekends fill up particularly fast, so the earlier you book, the better your selection.
That said, we do accept last-minute bookings when we have availability. We’ve had families call the day before their party and still get exactly what they wanted, though this isn’t something you should count on during busy season.
If you have a specific slide in mind or your party date is during a popular time like Memorial Day weekend or Fourth of July, booking a month ahead gives you the best chance of getting exactly what you want.
